Note 1669 — BOOK XXXIV. THE NATURAL HISTORY OF METALS.

There have been numerous opinions on the meaning of this word, and its signification is very doubtful. Beckmann has the following remarks in reference to this passage:—“In my opinion, this was the name given to pieces of steel completely manufactured and brought to that state which rendered them fit for commerce. At present steel comes from Biscay in cakes, from other places in bars, and both these were formerly called ‘stricturæ,’ because they were employed chiefly for giving sharpness to instruments, or tools, that is, for steeling them. In speaking of other metals, Pliny says that the finished productions at the works were not called ‘stricturæ’ (the case, for example, with copper), though sharpness could be given to instruments with other metals also. The words of Pliny just quoted are read different ways, and still remain obscure. I conjecture that he meant to say, that some steel-works produced things which were entirely of steel, and that others were employed only in steeling—‘ad densandas incudes malleorumve rostra.’ I shall here remark that these ‘stricturæ ferri’ remind us of the ‘striges auri,’ (see B. xxxiii. c. 19), such being the name given to native pieces of gold, which, without being smelted, were used in commerce.”—Hist.
